First you need to decide on the range of random numbers. Then use
rand(1) to generate and floating random number between 0 and 1, then
map the generated number to the range you want, and then chop of the
fractional part.

for example, if you want a random interger between 0 and 100, then
something like could be a solution

>> round(rand(1)*100)

ans =


if you want random intergers between 0 and 1000, then

>> round(rand(1)*1000)


if you want a random number between values other than 0 and some
positive upper limit, then you need to use a slightly more advanced
maping than the above. But the idea is the same. You use the random
number generated by rand(1) and map that to whatever you want.
